This invention relates to looms andmore particularly to looms ofthefilling replenishing type.

Looms of the above general character are now usually provided, with afeeler mechanism for effecting replenishment of filling from time totime and also with a filling fork mechanism for stopping the loom incase the filling fails. a

It may happen at times that the feeler mechanism will call forreplenishment of filling on the same detecting beat that the fillingfork mechanismcalls for loom stoppage, and oneof thepurposesof thepresent invention is to prevent the feeler mechanism from effectingreplenishment of filling when, on the same detectin'g beat, the "fillingfork mechanism operatesto effect loom stoppage.

The invention and new combination of parts willbest be made clear fromthe following description and the accompanying drawings showing one goodpractical form of the invention.

Fig. his a sectional-detail; V The-filling replenishing mechanism at theside of the loom opposite the fceler'mechw nism is not herein-showna-nddescribed in detail, because such details form nopart of the presentinvention and are now well understoodby those familiar with the art. Theloom frame 1 may be of usual construction and the side frames thereofare connected by the breast beam 2 upon the uppersurface of which ismounted the filling V fork stand Swhich supports the filling fork slide4. The filling fork slide has mounted upon its rear end portion at 5 thefilling fork 6 adaptedtoengage the filling on a detecting beat whenfilling is laidin the shed. The

filling fork 6 may be of usual construction and is provided-with theloop in the present instance, adapted to engage the shoulder 8 of amember 9 mounted upon the cam follower 10, the construction being suchthat should filling be laid by the shuttle and the lay be movedfrontwardly on its detecting beat, the filling fork will be tilted, asusual, and the loom will continue to run.

If, however, filling fails or is absenton a detecting-beat, the fillingfork will failto be tilted, whereupon the loop 7 will be engagedby thecam follower actuated member 9 and the filling fork slide will be movedfrontwardly to thereby effect loom stoppage.

Any suitable form of stopping mechanism maybe associated with thefilling fork slide, but as shown in the present instance of theinvention, the filling fork slide-ahas extending from one side thereofthe lug 11 which is engaged by one end of a-knock-offleverlQ pivoted onthezloom frame at 13 and having itsopposite end 14 resting against ashipper 15 normally held in running position in a notch 16 formed in theshipper stand 17.

This form stop nechanism'is well adapted for use in connection with thefilling form mechanism-and serves to'bring the 100mm rest when thefilling fork "detects absence of filling on a detecting beat.

Extending from the shipper stand 17 is an arm-18 on which is mounteda-feelerrstan d 19 for the support of afeeler 20. The feeler mechanismincluding the feeler stand, the fe'eler 20 and the associated parts, maybe of any suitable character, the essential in thisrespect-beingthatupon each detecting beat the feeler wilLdetectthecondition of the filling in="the shuttle and when it has reached acertain degree of exhaustion will call fora.

change of filling. The feeler mechanism illustrated in the presentinstance is, or may be, of the same general type as' shown and 7described more fully in'the 'BrownandRepass Patent, N0.1,593,426, datedJuly QO, V

The transmitter 21 extends laterally from the feeler stand and isconnected to a bell crank 22, one arm 23 of which is normally out of thepath of a cam follower actuated member 24. The bell crank 22 is mountedfor pivotal movement at 25 upon a sliding actuator 26, the constructionbeing such that should the feeler 20 be moved longitudinally of theshuttle on a detecting beat, it will raise the arm 23 of the bell crankinto the path of movement of the member 24, to thereby initiatereplenishment of filling, as will be later explained.

Extending transversely of the loom is the transverse or rock shaft 27which, as usual, is mounted in the brackets 28, one at each side of theloom. Secured to the rock shaft 27 is the upwardly extending arm 29having a bifurcated portion 30. The front end of the sliding actuator 26is provided with a slot 31 through which passes a pin 32, therebyconnecting the sliding actuator 26 with the upper end portion of the arm29.

From the construction thus far described it will be apparent that shouldthe sliding actuator 26 be moved frontwardly it will slide on the pin 32without effecting any rocking movement of the rock shaft 27 andconsequently not call for replenishment of filling. Since, however, thefunction of the sliding actuator 26 is to effect replenishment offilling by frontward movement of the sliding actuator under normalconditions of loom operation, the present invention provides a toggleconnection between the arm 29 and the actuator 26, such that the toggleis normally straightened and therefore prevents sliding movement of theactuator 26 relative to the arm 29.

One member 33 of said toggle connection is mounted on the pin 32 andpivotally connected at 34 with the companion toggle member 35, which isof the flat plate formation as shown, and which is pivotally connectedto the sliding actuator 26 at 36. Thus when the toggle is straight asindicated in the normal position of parts in Figs. 1, 2, the pivotalconnection at 34 of the toggle members will be below the pivotalconnection 36 of the toggle member with the sliding actuator, with theresult that the toggle will normally remain straightened in order totransmit frontward movement of the actuator 26 to the arm 29 secured tothe transverse or rock shaft 27.

It may be desirable at times to insure that the toggle will have itsmembers in straightened or stressed transmission relation, and to thisend the toggle member 33 is secured to the pin 32 by a cotter pin 37,and mounted upon the pin 32 where it extends laterally from the arm 29is a sleeve 38 about which is wound a coiled spring 39, one end of whichis secured to the sleeve at 40 and the other end to the arm 29 at 41,the result being that the tendency of the spring acting through thesleeve 38 which is secured to the pin 32, will be to hold the toggle instraightened position, as indicated in Fi s. 1 and 2. To preventoverthrow of the toggles under the action of the spring 89, the togglemember 35 has a stop 42 which overlies the sliding actuator 26 and has ahorizontal portion 43 to engage the top of the sliding actuator when thetoggle is straightened and the pivotal point 34 between the togglemembers is slightly lower than the pivotal connection 36 between thetoggle member 35 and the actuator 26, with the result that any frontwardmovement of the sliding actuator 26 will effect rocking movement of thetransverse or rock shaft 27 and replenishment of filling.

Pivotally connected to the toggle member 35 at 44 the toggle trip 45which extends rearwart ly and is provided with a lug 4i}, and extendingupwardly from the filling fork stand 3 is a fixed stop 47, theconstruction being such that when the lug 46 extending from the toggletrip engages the fixed stop rising from the lilling fork stand, thetoggle connection between the sliding actuator 26 and the arm 29 will bebroken and parts will take the position as indicated in Fig. 3, so thaton frontward movement of the sliding actuator 26, the transverse shaft27 will not be rocked and filling replenishment will not be called. Thisis the condition desired when the feeler mechanism calls forreplenishment and the filling fork ll'l-bti? anism on the same detectingeat ca ls for loom stoppage, and in order to control the position of thetoggle trip relative to the stop 4?, the filling fork slide 4 haspivotally connected thereto at 48 a toggle trip controllei 49 which hasa head portion 50 provided with an incline 51 adapted to contact with asimilar incline 52 formed on the to trip. Under normal condition ofparts indicated in 1 and 2, the incline 51 of the trip controller 49 isrearward of the fixed stop 47, with "he result that the incline 52 onthe tog trip, and 51 on the trip controller, in serve to lift the toggletrip to carry the lug 46 above the stop when the feeler 47 calls forreplenishment of filling and the filling fork mechanism is not actuatedto cal for loom stoppage. ing fork mechanism calls for loom stoppage dueto absence of filling laid in the shed, the filling fork slide 4 will bemoved frontwardlv, thereby carrying the trip controller 49 frontwardlyand permitting the lug 46 on the toggle trip to remain in position toengage the fixed stop 47 as the sliding actuator 26 is moved frontwardlyby the cam follower. Under these conditions the toggle trip will beprevented from moving frontwardly with the sliding actuator 26, andowingto its pivotal connection with the toggle member 35 will trip thetoggle from the position of Fig. into that of Fig. 3, so that the togglewill hen, however, the fillion lit)

not transmit frontward movement of the actuator 26 to the arm 29, andthe actuator 26 will move idly frontward by reason of the pin and slotconnection with the arm 29.

Under normal weaving conditions when filling is laid in the shed, thefeeler mecha-c nism will act as usual to effect replenishment of fillingfrom to time, so, also, the filling fork mechanism will act to effectloom stop page when filling fails to be laid inthe shed while there yetremains a working supply of filling in the shuttle. If, however, thefeeler calls for replenishment of filling from any cause and the fillingfork mechanism calls for loom stoppage by reason of failure of filling,on the same detecting beat, thefeeler mechanism will be prevented fromeffecting replenishment of filling and the loom will stop under thedictates of the filling fork mechanism.

In the present illustration of the invention, the transverse shaft 27has loosely mounted thereon the hub 54 of an arm 55 which serves as aconvenient pivotal connection, as at 48,

for the trip controller 49 which, of course, is movable towards and fromthe front of the loom with the filling fork slide. i
